It is necessary to make sure that from any given point within a building people have clear directional guidance on how to reach the designated place of safety. These instructions are given by using standard escape route signs along the escape route.

The evacuation safety system is comprised of signs positioned above doors and along the escape routes indicating all changes of direction leading to the designated point of safety. It is essential that when reaching a sign people can already see the next one and continue that way until the final exit.

All escape route signs should generally be installed within the 1.8m - 2.5m height range.
